Ton, 7071/0112 it may concern:

Be it known that I, CHARLES H. HOPMANN, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Metallic Windows, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in metallic windows; and the principal object of my invention is to simplify and improve the general construction of the metallic window patented by me June 6, 1905, No. 791,909.

A further object of my invention is to so construct a metallic window as that the sash may be easily and quickly positioned in or removed from the frame.

A further object of my invention is to construct a window-frame with removable sections on its inner faces in order that the sash weights and tapes may be easily and quickly placed in position and adjusted or fixed if they should become inoperative.

To the above purposes my invention consists of certain novel features of. construction and arrangement of parts, which willbehereinafter more clearly set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 is a vertical section taken through the center of a window of my improved construction. Fig. 2 is a vertical section taken through the upper corner of the frame of my improved window and approximately on the dotted line 2 2 in Fig. 3. Fig. 3 is an enlarged horizontal section taken through the center of the window-frame and showing both of the sash in section. Fig. i'is a horizontal section taken through the top portion of the window-frame and showing the pulleys over which the window-tape travels. Fig. 5 is a perspective view of a portion of a springactuated parting-strip I make use of in carrying out my invention.

Referring by numerals to the accompanydrawings, 1 1 designate the vertically-arranged side portions of the window-frame, which are preferably constructed of suitable sheet metal; 2, the base or sill of the frame, and 3 the top thereof. Formed in the outer walls at of the vertical portions 1 are the vertically-extending grooves 5,. which are formed by bending the sheet metal outwardly, and formed on each inner wall 6 are the outwardlyprojecting vertically -.arranged grooves 7,

which are formed by bending the sheet metal outwardly. Soldered to the rear faces of the edges of the sheet metal adjacent the bends that form the grooves 7 are nuts 8, and the space between the edges of the metal adjacent each pair of grooves 7 is closed by removable sections which complete the walls forming the faces of the side portions 1 of the window-frame and which extend from the sill 2 to the top 3. One of these removable sections comprises a plate 9, having its side edges 10 bent rearwardly to fit into a corresponding pair of grooves 7. The center of this plate 9 is bent to form a vertically-arranged pocket 11, which extends the entire length of said plate 9, and from the rear side of said pocket 11 the plate is doubled, as indicated by 12, and extends rearwardly, and its extreme outer edge occupying the corresponding one of the grooves 5. Thus the side portion of the frame 1 is formed into two compartments in which the sash-weights operate.

Formed at the point where the walls of the pocket 11 and the face of the plate 9 join are retaining-lips 13, which are in the same plane with the face of said plate 9 and which extend toward one another. Screws or bolts 14 pass through the outer edges of the plate 9 into the corresponding nuts 8, and thus rigidly retain said plate 9 in proper position to close the opening in the corresponding side of the frame 1. The opening in the opposite side of the framel is closed by a plate 15, the front and rear edges of which are bent outwardly and occupy the corresponding grooves 7. Small screw-bolts 16 pass through the outer edges of this plate 15 and enter the corresponding nuts 8. Formed at the center of this plate 15 is a pair of vertically-extending ribs 17, which project toward the plate 9 and which form on the rear side of the plate 15 a pair of grooves, which are occupied by the forward ends of apair of plates 18, forming a vertical partition in this side of the frame 1. The outer ends of these plates 18 occupy the corresponding one of the grooves 5.

A spring-actuated parting-strip (see Fig. 5) is movably arranged in the pocket 11 and extends vertically throughout the length of said pocket, which strip comprises a sheetmetal plate 19, the side ed es of which ongage behind the lips 13, and formed in the center of said strip is a pair of forwardly-projecting vertically-extending ribs 20, which IIO project slightly beyond the face of the plate 9. Riveted to the rear face of this strip 19 at suitable distances apart are leaf-springs, such as 21 ,the free ends of which bear against the rear wall of the pocket 11, and thus normally retain the parting-strip with its ribs 20 projecting beyond the face of the plate 9.

Formed in the bottom plate'or portion of the top rail 3 of the frame immediately over the side frames 1 are the openings 22. pair of transverse bars 23 are detachably secured in the ends of the portion 3 of the frame immediately over the openings 22, and arranged on each pair of bars is a pair of bearings 24, which carry the grooved pulleys 25, over which the window-tapes travel.

Arranged to slide vertically in the windowframe in the usual manner is a pair of sash 25, the frames of which are constructed of sheet metal bent into regular form, and formed in the outer faces of the vertical side rails of each sash are the grooves 26, in which the corresponding ribs 17 and 20 are located when the sash are in position in the windowframe. Suitable sections of metallic windowtape 27 are secured in the usual manner to the Window-sash and pass upwardly over the pulleys 25 and from thence downwardly into the spaces within the side portions of the window-frame, and the lower ends of said sections of tape carry the sash-balancing weights 28.

After a window-frame of my improved construction has been set up in position and it is desired to place the window sash therein the yielding parting-strip 19 is moved backwardly into the pocket 11 in any suitable manner to the position shown by dotted lines in Fig. 3, and the sash are now engineered or manipulated into position so that the ribs 17 engage in the grooves 26 at the left-hand sides of said sash. The parting-strip is now released from its depressed position, and the springs 21 will force said parting-strip out wardly and cause the ribs 20 thereon to engage in the corresponding grooves 26 in the right-hand side rails of the sash. The sash may now be elevated and lowered, as desired, in the usual manner, and to remove said sash from the frame it is only necessary to depress the parting-strip '19 or move the same backwardly into the pocket 11 in order to pull the right-hand sides of the sash outwardly and'then disengage the left-hand sides from the frame.

The plates 9 and 15 are removablein order that the sash-balancing weights and tapes may be inserted in position and inorder that access may be had thereto while being repaired or adjusted, and the openings 22 permit the tape to be adjusted-over the pulleys 25*.

A metallic window-frame of my improved construction permits the window-sash to be readily inserted or removed from position, permits the sash to operate vertically, very easily and uniformly, and possesses superior advantages in points of simplicity, durability, and general efficiency.

I claim 1. A metallic window, provided with a vertically-arranged pocket in one of its side frames, and a spring-actuated parting-strip arranged in said pocket substantially as specified.

2. In a metallic window, a frame provided in one of its sides with a vertically-arranged pocket, a parting-strip arranged to be depressed into said pocket, and springs arranged in said pocket behind the partingstrip; substantially as specified.
